Accompanied by a bikini-clad blonde who is believed to be Chantel Jeffries, 21 – a model who was with the singer when his yellow Lamborghini was pulled over by police in Miami for drag-racing on Thursday morning – Bieber drank a few beers and rode a jet-ski on Punta Chame beach, according to Panamanian website Telemetro.

On Thursday Bieber was charged with DUI, driving without a valid driver's license and resisting arrest, and was released on $2,500 bail after appearing before a judge.

The singer, who is also under investigation for allegedly throwing eggs at a neighbors home in L.A. earlier this month, waved to fans from the top of an SUV after his release from jail, and later compared himself on Instagram to Michael Jackson, who was pictured in the same pose in 2004.

PEOPLE has confirmed that Bieber is in Panama and fans began posting pics of the star as soon as he arrived at the airport.

The singer and his friends were surrounded by onlookers on the beach on Saturday, and one posted video of the relaxed-looking singer tossing around a football. The video has since been taken down.
